The laboratory standard Cryptococcus sp. reference strains, deposited by K.J. Kwon-Chung, represent the eight molecular types of Cryptococcus neoformans and Cryptococcus gattii. These strains are useful tools for the identification of clinical or environmental isolates, and for epidemiological studies.

ATCC's Preceptrol cultures offer an economical way for your lab to use well-characterized ATCC strains. Most preceptrol cultures are packaged in convenient serum vials, and afforded the same standards of quality as our traditional batch vial preparations.

ATCC offers fully characterized strains for quality control testing, including strains that have been recommended as controls for rapid identification, tests on food and water, and use with commercial kits and instrumentation.
